ObjectiveTo evaluate the correlation between the promoter polymorphism of Fibroblast Growth Factor 1 (FGF-1) and late-onset Alzheimer's disease (LOAD). MethodsClinic pathological data from 206 autopsies were analyzed, including 100 autopsy-confirmed LOAD patients and 106 age-matched non-demented controls. PCR-RFLP (Restriction fragment length polymorphism) approach was used to determine the genotype of the promoter polymorphism of FGF-1 gene. ResultsThe genotyping frequencies of the promoter polymorphism (-1385 A/G) were AA 20 (10%), GA 89 (43%), GG 97 (47%), respectively. There was significant (P=0.027) difference of genotyping frequencies between the cases and controls; GG genotype was positively associated with LOAD (odds ratio=2.02, 95%CI:1.16～3.52). ConclusionThe promoter polymorphism (-1385 A/G) of FGF-1 gene was associated with LOAD.

This paper intends to explore the color changes considered to be Maillard reaction during the process of Chinese herbal medicine. The Maillard reaction products (MRPs) are often in substantial proportions of Chinese herbal compound decoctions but their effects are often neglected. By considering the effects of MRPs in studies of effective components on Chinese herbal compounds, a new perspective is established in future researches of Chinese herbal compound decoctions.

OBJECTIVETo investigate the effects of saponins from Anemarrhena asphodeloides Bunge (SAaB) (Botanical Name: Anemarrhena Asphodeloidis Rhizoma) on the growth of vascular smooth muscle cells (VSMCs).

METHODSCell proliferation was measured by a newly developed cell proliferation reagent, WST-1. Cell apoptosis was assayed by flow cytometry through detecting annexin V. Nitric oxide production was evaluated using confocal laser scanning microscopy with diaminofluorescein diacetate (DAF-2, DA). Cell aldose reductase (AR) activity, as well as the effect of Epalrestat and interleukin-1beta were also explored.

RESULTSWST assay showed that cell proliferation induced by serum was significantly inhibited by SAaB (P<0.01). Flow cytometry analysis revealed that SAaB could enhance apoptotic rate of VSMCs (P<0.01). Nitric oxide production was significantly enhanced after administration of SAaB and interleukin-1beta. Moreover, AR activity of VSMCs was also remarkably inhibited by both SAaB and Epalrestat (P<0.01).

CONCLUSIONSAaB can inhibit proliferation and enhance apoptosis of VSMCs. It may protect vascular cells by inhibiting VSMC proliferation and augmenting apoptotic rate of VSMCs via NO-dependent pathway.

OBJECTIVETo probe into the mechanisms of moxibustion and Chinese herbs in delaying aging.

METHODSSixty SD rats were randomly divided into a young control group, an aging group, a moxibustion group, a Chinese herb group and a moxibustion plus Chinese herb group. In the latter 4 groups, aging rat model was established by hypodermic injection of D-galactose. In the course of modeling, the 3 treatment group were treated by mild-warm moxibustion at "Zusanli (ST 36)", "Shenshu (BL 23)" and "Guanyuan (CV 4)" with reinforcing method, stomach perfusion of decoction of Liuwei Dihuang plus Danggui (Angelica) and Danshen (Salvia Miltiorrhiza Bge), and the moxibustion plus the Chinese herbs, respectively. After treatment for 40 days, liver mitochondrial DNA, serum IL-2 and IL-6 contents were detected.

RESULTS(1) The mitochondrial DNA content of liver cells and serum IL-6 level significantly increased (P < 0.05, P < 0.01) and serum IL-2 level significantly decreased (P < 0.05) in the aging model group as compared with those in the young control group. (2) The mitochondrial DNA content of liver cells and serum IL-6 level significantly decreased (P < 0.05, P < 0.01) and serum IL-2 level significantly increased (P < 0.05) in all the treatment group as compared with those in the aging model group.

CONCLUSIONMoxibustion and Chinese herbs function delaying aging though decreasing mitochondrial DNA content of liver cells and serum IL-6 level and increasing serum IL-2 level.

Purpose To investigate the clinicopathological features of primary subcutaneous lymphomatoid granulomatosis (LYG). Methods A case of primary subcutaneous LYG was observed by analysis of the clinical, histological features, immunophenotype and molecular pathology with review of the related literature. Results The male patient, 78-year-old, inadvertently found a mass of right axillary for more than 10 days. The boundary of the mass was clear, it seemed to have a capsule, the cut surface was grayish yellow and grayish red, the texture was medium. A large amount of coagulative necrosis was observed in the center of the mass under microscope. The peripheral area showed a morphological change of panniculitis, accompanied by pleomorphic lymphoid infiltration, showed central and vascular destructive infiltration, pathological mitosis was occasionally observed. Immunophenotyping showed that atypical large lymphoid cells expressed CD45 RB, CD20, CD30, while CD3, CD15, CD56, TIA-1, Granzyme B, ALK, CD21, Langerin and CD1 a, S-100 and CK (AE1/AE3) were negative. The proliferation index of Ki-67 ranged from 50％ to 60％. EBER in situ hybridization showed that positive cells were> 20/HPF.Neither acid fast staining nor TB-DNA testing supported tuberculosis. Molecular pathology found clonal Ig K gene rearrangement, TCRB + TCRG gene rearrangement showed the absence of monoclonal proliferating T cell population. Conclusion The primary subcutaneous LYG is a rare tumor. which can be diagnosed by combination of morphology, immunophenotype and molecular pathology.

Objective To explore the best methods and skill for the removal of difficult and high risk tracheobronchial foreign body under bronchoscope.Methods A retrospective review was performed between August 1995 to August 2012.There were 4217 children with tracheobronchial foreign body,among them,272 were diagnosed as high-risk,highly difficult tracheobronchial foreign bodies confirmed by clinical manifestations,foreign body type and bronchoscopy.Results In 271 children,the tracheobronchial foreign body was removed under bronchoscope,the success rate was 99.6％ ; only one child with a pen cap blocking the left lower lobe bronchus was transferred to the department of thoracic surgery,and the foreign body was finally removed by thoracotomy.Eighty-five children (among them,82 children were under 1 year of age)had Ⅱ-Ⅱ degree laryngeal obstruction,the emergency surgery was performed to remove the foreign body and to relieve the laryngeal obstruction.Twenty-six children had lung infection and 27 children had failed foreign body removal surgery before,in all these children,the foreign body was removed after infection control.There were 17 children with the pen cap as the tracheobronchial foreign body,direct removal was successful in 12 children with the history less than two weeks; in 4 children,the foreign body was removed after 0.1％ epinephrine saline flush,and 1 case with the homemade bronchial foreign body hook remove.There were 26 children with the whistle as the foreign body,and 32 children had large and sharp foreign bodies.In these cases,the foreign bodies were removed together with the bronchoscope.Forty-two children had multiple or fragile foreign bodies,and 16 children had subsegmental bronchial foreign bodies.In these cases,the foreign bodies were removed with forceps under direct vision and intraoperative bronchial lavage.In This series,129 children received intraoperative bronchial lavage,among them,127 children showed normal X-ray changes one week after operation.Two children with a history of more than 1 month complicated with pulmonary consolidation.After bronchial lavage,pneumothorax and subcutaneous emphysema occured,which recovered after treatment.No glottic edema,asphyxia,and other complications were found,the complication rate of surgery was 0.7％.Conclusion For the removal of highly difficult and high risk tracheobronchial foreign bodies,preoperative analysis and discussion shoule be sufficient,appropriate surgical skill and surgical instruments may improve the success rate of the surgery and prevent the operation complications.

OBJECTIVEThe main purpose of this work was to give the evidence of reasonable and feasible dust control measures which will be taken in the future by analyzing the trend of dust concentration from 1991 to 2010 and identifying working faces with the severe dust contamination in one underground iron mine.

METHODSThe data was from routine monitoring between the years 1991 and 2010, which enclosed the total dust concentrations and silica contents. China National Standard of Occupational exposure limits for hazardous agents in the workplace used to judge whether the dust concentration exceeded the National Standard.

RESULTSThe general trend of total dust concentration from 1991 to 2010 was decreased, especially maximum and average levels. The highest exceeding rate was 43.16% in 1993 and the best years were 2009 and 2010, but the exceeding rates were still over 30%. The dust exposure levels varied with different work faces. The mining and supporting were the most severe dust pollution faces which the highest ultra exceeding rates were 51.61% and 51.48% and the maximum exceeding times were 64.6 and 16.4 respectively. The next was constructing face with 40.23% exceeding rate and 24.6 times more than standard.

CONCLUSIONThe trend of total dust concentration from 1991 to 2010 was decreased, but the dust exceeding rate was still high. The strong measures should be taken to control the dust pollution in this iron mine, especially mining and supporting faces.
